LAS VEGAS -- The gunman who killed four people before taking his own life in a midtown Manhattan office building that houses the NFL's headquarters had for years sought medical help for frequent, debilitating headaches -- including receiving injections in the back of his head, a person close to the man's family told ESPN.
Shane Tamura, a 27-year-old Las Vegas casino worker, had regularly met with doctors, including a neurologist, and received yearly MRI exams and various treatments seeking to diagnose the cause and stop the pain, said the source who spoke on the condition of anonymity.
